[Opsys Aliases] This section will replace an operating system indentifier with an internal alias. This alias is used in the fourth colon delimited field of a mapping rule.This example will map anything containing the substring 'java' to an alias of 'java'. Two variations of windows are given an alias of 'msdos'. Everything else will be matched to .* so it is mapped to the alias 'other'.[Opsys Aliases] java = java win32|msdos = msdos .* = other
